Affected versions of this package are vulnerable to Improper Authorization via the refreshOperation function in packages/payload/src/auth/operations/refresh.ts, where the collection associated with the authenticated user's token is not validated against the target collection during a token refresh request. An authenticated user belonging to one auth-enabled collection can supply their token to the refresh endpoint of a different auth-enabled collection, potentially obtaining a valid token for that collection and gaining unauthorized read access to its data.
